Insert an expression or use NEXTVAL as value

[zinefer]

This is more of a question than an issue.

I would like to run an insert with a database calculated value, like:

INSERT INTO "users" ("id", "name") values (NEXTVAL("users_id_sequence"), "jake");

Is there some mechanism I can use to prepare an insert statement to use with a model or maybe a way to temporarily disable the quoting?
